Reaction Steps

To a stirred solution of methyl 4-[5-(R)-phenyl-2-(S)-pirrolidinylmethoxy]benzoate (125 mg, 0.40 mmol), 4-[N′-(2-bromophenyl)ureido]-3-methylphenylacetic acid (146 mg, 0.40 mmol) and N,N-dimethylaminopyridine (49.0 mg, 0.40 mmol) in DMF (10 ml) was added EDC.HCl (84.1 mg, 0.44 mmol) at rt, and the resulting mixture was stirred for 6 h. The reaction mixture was poured into water and extracted with EtOAc. The organic layer was washed with brine, drying over anhydrous Na2SO4, then concentrated in vacuo. The residue was chromatographed on silica gel with hexane-EtOAc (1:4) as eluent to give methyl 4-[1-[4-[N′-(2-bromophenyl)ureido]-3-methylphenylacetyl]-5-(R)-phenyl-2-(S)-pyrrolidinylmethoxy]benzoate (238 mg, 90%) as a colorless amorphous solid. 1H-NMR (CDCl3) δ1.92 (s, 3 H), 2.09-2.27 (m, 3 H), 2.42-2.50 (m, 1 H), 3.22-3.41 (m, 2 H), 3.88 (s, 3 H), 4.39 (d, J=4.4 Hz, 1 H), 4.64 (brs, 1 H), 5.00 (t, J=6.8 Hz, 1 H), 6.72 (s, 1 H), 6.81-6.93 (series of m, 8 H), 7.22-7.42 (series of m, 6 H), 8.01 (d, J=8.4 Hz, 2 H), 8.13 (d, J=8.0 Hz, 1 H ); MS (FAB) m/z, 656 (M+), 658 (M++2).
